To improve a machine tool, comprising a machine frame, a workpiece holder arranged on the machine frame for a workpiece to be machined, a tool holder arranged on the machine frame for receiving a tool and at least one drive with a slide for executing a relative movement between the tool and the workpiece in the direction of at least one axis, such that it allows as high dynamics as possible, it is proposed that the drive comprise electric linear motors aligned parallel to the axis and spaced from one another in a transverse direction, that the slide extend between the two linear motors, and that a control be provided for simultaneously operating the linear motors for displacement of the slide.

Machine tool

In order to improve a device for the non-circular machining of workpieces comprising a machine frame, a workpiece spindle held on the machine frame and operated as C-axis for a workpiece to be machined, a Z-slide displaceable on the machine frame in the Z-direction in relation to the workpiece spindle and having a Z-axis drive, an X-axis drive in the form of a linear motor arranged on the Z-slide for advancing a tool in the X-direction towards the workpiece, and a numerical control system for activating the X-axis drive in correlation with the rotation of the workpiece spindle, such that more precise work results are obtained, it is proposed that the linear motor serving as X-axis drive be a three-phase asynchronous linear motor with a primary part fixedly arranged in the X-direction on the Z-slide and a secondary part movable relative to the primary part.
